I'm a retired Soldier but work as a building materials sales rep and spend as much of my leisure time in the outdoors as I can (mostly hunting and fishing). My three top knife patterns (three I could get along with if that was all I could have) are:
1.) EDC for work and leisure - Medium size Stockman from 3-3/8" to 3-3/4". My top favorites are the two Case Medium Stockman patterns 6318 & 6332, but also carry a Buck 303 or Schrade USA 34OT. Work use leans heavily on the Sheepfoot for scoring drywall. The other blades get used for any purpose needed (including cutting food, I'm not choosy about retaining a special blade for that use).
2.) General outdoors use (to include cutting up game and fish) - Buck 110 - normally in regular weight and sometimes in the lightweight versions. I will also substitute a Buck 112 or Case Hammerhead on occasion. Good bait knife and good skinning knife - I use it as a backup to my fixed blade when gutting an animal, just in case I get one tainted - don't want the meat to get contaminated by animal excretions.
3.) Specifically for game cleaning (prefer over the 110 for this purpose) - Buck 118, best deer hunters knife I have ever owned. I will substitute a Buck 102 for waterfowl and pheasant, and a Buck 121 for cleaning fish and wild turkey (the flexible blade works great when breasting).
